A resolution establishing the rules and regulation in respect
to procedure before the Town Planning Board of the Town of
Busti, County of Chautauqua, New York in respect to the approval
or disapproval of plans submitted to the said Planning Board,
pursuant to Section 276 and 277 of the Town Law and in respect
to the dedication and acceptance of Town Highways.
Any individual, individuals or corporation
desirous of conveying ownership of any road to the Town of
Busti shall so signify their intent by filing with the Town
Highway Superintendent and Town Board plans defining the location,
grade and alignment of said road, and a map and description
defining the boundaries of the property to be conveyed to
the Town. Said plans shall show the proposed roadway alignment,
grade, cross section and drainage facilities and shall be
prepared by a licensed Professional Engineer or a licensed
Land Surveyor where permitted by State law. Said map and description
shall be prepared by a licensed Land Surveyor or an exempt
Professional Engineer. The Town Board and the Town Highway
Superintendent shall review said information to ascertain
whether acceptance for maintenance and operation is in the
best interest of the Town. Should the Town Board and Town
Highway Superintendent agree to accept said roadway, said
acceptance shall be conditional upon the roadway being constructed
in accordance with the following specifications. Failure to
construct the roadway and its related appurtenances in accordance
with, or in excess of, these specifications shall cause the
Town Board and Highway Superintendent to deny acceptance of
the completed roadway.

LAW

in PDF Format
- The highway right-of-way shall be no less than fifty feet (50') wide.
The highway shall be centered in the right-of-way.
- The roadway shall consist of 12 inch (compacted thickness) of gravel
(approved by the Town Highway Superintendent), topped with
an additional 4 inches of compacted screened No. 1 gravel.
Basic dimensions and pertinent information are shown on
the attached "Typical Roadway Section".
- Adequate roadside drainage, in the form of ditches where necessary, shall
be constructed. Internal storm drainage systems with drop
inlets, catch basins and manholes shall generally not be
acceptable because the Town does not have the equipment
to property maintain such facilities. The depth of ditches
shall not be less than eighteen inches (18” below the shoulder
of the road). Where driveway culverts larger than twelve
inches (12”) diameter are required, the ditch depth shall
be increased accordingly. The slope from the shoulder edge
to the ditch (fore slope) shall be no steeper than 1 vertical
to 4 horizontal. The slope from the ditch to existing ground
beyond the ditch (back slope) shall be no steeper than 1
vertical to 2 horizontal. All components of ditches (fore
slope and back slope) shall be within the dedicated right-of-way.
Where this cannot be accomplished within the specified fifty
foot (50’) right-of-way, the right-of-way shall be widened
or a permanent drainage easement contiguous to the right-of-way
shall be conveyed. All ditches shall be sloped longitudinally
not less than 0.5% (0.5 feet in 100 feet) to provide drainage.
All ditches shall drain to an adequate outlet (stream, roadside
ditch or established water course). Where the drainage outlet
is located outside the right-of-way, a permanent drainage
easement not less than thirty feet (30’) in width shall
be conveyed to the Town. Where drainage is carried across
the roadway, culverts of adequate size and construction
shall be installed. The sizes of all culverts shall be determined
from engineering calculations. As a minimum, such culverts
shall be eighteen inches (18”) in diameter and shall have
at least twelve inches (12”) of cover at any point between
shoulder breaks. Larger culverts shall be installed when
drainage calculations indicate they are necessary.
- Prior to installation of roadway gravel, the entire right-of-way shall
be cleared and grubbed. All topsoil, vegetation and unsuitable
materials located in areas where gravel is to be installed
shall be completely removed and replaced with granular material
meeting the Highway Superintendent's approval. This material
shall be graded and suitably compacted to provide a firm
and solid subgrade for the placement of roadway gravel.
Where excavations are necessary to install gravel, the native
materials shall be compacted, to the Highway Superintendent's
satisfaction, to provide a firm and solid subgrade for the
placement of roadway gravel. The subgrade shall be sloped
one-half inch (1/2”) per foot to each side of center line.
- After acceptable preparation of subgrade, highway gravel shall be installed
in three lifts and suitably compacted. Each lift shall be
not more than eight inches (8”) or less than four inches
(4”) thick. The total thickness after compaction shall be
not less than sixteen inches (16”). The gravel shall extend
beyond the shoulder break and into the fore slope of the
ditch to allow water within the gravel to drain. Highway
gravel shall contain no stones larger than four inches (4”)
in size, shall be uniformly graded and contain less than
ten percent (10%) fines (passes a No. 200 sieve). The finish
surface shall be not less than thirty feet (30’) wide and
shall be sloped one-half inch (1/2”) per foot away from
the centerline to insure positive drainage of the roadway
surface.
- To the extent possible the roadway centerline shall be tangent. Where
necessary, curves meeting AASHTO Standards, may be utilized.
Except at intersecting roadways, no curve shall be less
than twenty-one (21) degrees. The preferred minimum curvature
shall be seven (7) degrees. Where deemed necessary for driver
safety, the roadway surface shall be super elevated with
the curve. Super elevation runoffs of adequate length, as
defined by AASHTO, shall be provided at the beginning and
end of each curve. At intersecting roadways, the corner
radii shall be not less than twenty-five feet (25’). Dead
end roads shall have a cul-de-sac with a minimum radius
of fifty feet (50’) to the outside of the roadway.
- The roadway grades shall be not less than 0.5% (0.5 feet in 100 feet)
and shall be no greater than 10%. All changes in grade shall
be accomplished with vertical curves of sufficient length
to provide eight distances (stopping and headlight) meeting
AASHTO Standards. Under no circumstances shall such eight
distances be less than 200 feet.
- All utilities (water, sewer, gas, electric, telephone, cable TV, etc.)
shall be permitted longitudinal occupancy within the highway
right-of-way or drainage easements. All such utilities shall
be located outside of the rights-of-ways and easements conveyed
to the Town, except where roadway crossing are necessary.
Where utility services are anticipated, they shall be located
in a separate easement at least fifteen (15’) in width adjacent
to the public right-of-way. Public utilities (water and
sanitary sewers) maybe located within the public right-of-way
with the prior consent of the Town Highway superintendent
and Town Board. Where said public utilities are intended
to serve adjacent properties that are to be developed at
some future date, the service laterals shall extend to the
limits of the right-of-way.
- Intersections with existing or proposed roads shall be
preferably ninety (90) degrees but shall not be less than
seventy-five (75) degrees.
